Vertical tail buffeting at high angles of attack is a phenomenon associated with the impact of
vortical flows generated by the aircraft on the fins. This poses a serious problem for both …

This paper gives an overview of the NASA F-18 High Alpha Research Vehicle. The three
flight phases of the program are introduced, along with the specific goals and data examples …

A 1/6-scale F-18 wind-tunnel model was tested in the Transonic Dynamics Tunnel at the
NASA Langley Research Center as part of the Actively Controlled Response Of Buffet …

This paper discusses the structure of the flow within the engine inlet of an uninhabited
combat air vehicle (UCAV). The UCAV features a top-mounted, serpentine inlet leading to …

Vertical tail buffeting is a serious multidisciplinary problem that limits the performance and

THE ability to fly and maneuver within the high-angle-ofattack regime gives the fighter pilot a
distinct advantage over his adversary. However, for twin-tailed fighters such as the F/A-18 …

Detailed wind tunnel and flight investigations were performed on the F/A-18 configuration to
explore the causes of many high-angle-of-attack phenomena and resulting disparities …
